One of the first panel sessions I went to featured a talk by Jeff Harris, of the Alliance to Save Energy.
He covered a lot of ground in defining “net-zero energy,” covering state and federal goals around NZE, detailing many of the appeals of NZE, and then focusing on the potential of NZE communities.
What I found most interesting during his talk was the specific examples of the military’s focus on getting a number of bases to NZE. He noted that there are more than 6 pilot sites targeting ZNE (often used interchangeably with NZE) by 2020. Two of the sites have the additional aggressive goal of being “triple-net-zero,” or net zero energy, water, and waste.
He also mentioned a specific site – Fort Carson – and showed some analysis (I think by the National Renewable Energy Lab, NREL) of what kinds of strategies and systems will be needed to achieve the ZNE goal.
After the session, I found an NREL report online that provides significant detail on the recommendations provided for Fort Carson” “Targeting Net Zero Energy at Fort Carson: Assessment and Recommendations” (link opens a PDF).

A few days ago, appliance manufacturers and energy efficiency advocates announced an agreement to call for new national minimum efficiency standards to improve energy and water efficiency standards for refrigerators, freezers, clothes washers, clothes dryers, dishwashers, and room air conditioners. The coalition of major appliance manufacturers, their trade union, and the energy efficiency advocates propose that the new national minimum efficiency standards and tax credits be instituted through action by the Department of Energy and by Congress.
According to the press release, the recommended standards and tax credits would save more than 9 quads of energy over 30 years. The recommended water efficiency standards and tax credits for clothes washers and dishwashers would save about 5 trillion gallons of water over 30 years.
Below, I’ve put together a rough timeline of how the proposed standards would take effect:
- January 2013 – dishwashers would see 14% energy savings and 23% water savings
- January 2014 – new refrigerator and freezer energy reduced up to 30%
- June 2014 – room air conditioners would increase in efficiency 10-15%
- 2015 – top loading clothes washers would have 26% energy savings and 16% water saving compared to current standards
- 2015 – front loading clothes washers would have 43% energy savings and 52% water savings compared to current standards
- 2015 – clothes dryers will increase in efficiency 5%
- 2018 – top loading clothes washers would have 37% energy and water saving compared to current standards
An overview of the agreement is here.
The agreement was signed by major appliance manufacturing members of the Association of Home Appliance Manufacturers (AHAM) and by major energy and water efficiency organizations, consumer groups and environmental organizations including the American Council for an Energy-Efficient Economy, Alliance for Water Efficiency, Alliance to Save Energy, Appliance Standards Awareness Project, Consumer Federation of America, National Consumer Law Center, Natural Resources Defense Council, Northwest Power and Conservation Council, and Northeast Energy Efficiency Partnerships.
